>From 1964 to 1966, Dr. Chu worked on the design of large-scale
computers at IBM in San Jose, California. From 1966 to 1969, his
research focused on computer communications and distributed databases
at Bell Laboratories in Holmdel, New Jersey. He joined the University
of California, Los Angeles in 1969. He has authored and co-authored
more than 100 articles and has edited three textbooks on information
technology and also edited a reference book (co-edited with T.Y. Lin)
on data mining.

During the first two decades of his research career, he focused
on computer communication and networks, distributed databases, memory
management, and real-time distributed processing systems. Dr. Chu has
made fundamental contributions to the understanding of statistical
multiplexing, which is widely used in current computer communications
systems and which influenced the development of the asynchronous
transfer mode (ATM) networks. He also did pioneering work in file
allocation, as well as directory design for distributed databases and
task partitioning in real-time distributive systems. This work has
influenced and has been applied in the design and development of Domain
Name Servers for the web as well as in current peer-to-peer (P2P) and
grid systems. Dr. Chu was awarded IEEE fellow for his contribution in
these areas.

During the past decade, his research
interests have evolved to include intelligent (knowledge-based)
information systems and knowledge acquisition for large information
systems. He developed techniques to cluster similar objects based on
their attributes and represented this knowledge into Type Abstraction
Hierarchies to provide guidance in approximate matching of similar
objects. Using his methodology for relaxing query constraints, Dr. Chu
led the development of CoBase, a cooperative database system for structured data, and KMed, a knowledge-based multi-media medical image system. CoBase
has been successfully used in logistic applications to provide
approximate matching of objects.

Together with the medical school staff, the KMed project has been extended to the development of a Medical Digital Library,
which consists of structured data, text documents, and images. The
system provides approximate content-matching and navigation and serves
as a cornerstone for future paperless hospitals. In addition, Dr. Chu
conducts research on data mining of large information sources,
knowledge-based text retrieval, and extending the relaxation
methodology to XML (CoXML)
for information exchange and approximate XML query answering in the Web
environment. In recent years, he also research in the areas of using
inference techniques for data security and privacy protection (ISP).

Dr. Chu has received best paper awards at the 19th International Conference on Conceptual Modeling
in 2000 for his work (coauthored with D. Lee) on XML/Relational schema
transformation. He and his students have received best paper awards at
the American Medical Information Association Congress in 2002
and 2003 for indexing and retrieval of medical free text, and have also
been awarded a "Certificate of Merit" for the Medical Digital Library
demo system at the 89th Annual Meeting of the Radiological Society of North America in 2003. He is also the recipient of the IEEE Computer Society 2003 Technical Achievement Award for his contributions to Intelligent Information Systems.

Dr. Chu was the past ACM SIGCOMM chairman from 1973 to 1976, an associate editor for IEEE Transactions on Computers
for Computer Networking and Distributed Processing Systems (1978 to
1982) and he received a meritorious award for his service to IEEE. He
was the workshop co-chair of the IEEE First International Workshop on Systems Management (1993) and received a Certificate of Appreciation award for his service. He served as technical program chairs for SIGCOMM (1975), VLDB (1986), Information Knowledge Sharing (2003), and ER (2004), and was the general conference chair of ER (1997). He has served as guest editor and associate editor for several journals related to intelligent information systems.
